This makes essentially for endless filter types.
3 Pole Parallel Low Pass
6 Pole Low Pass
Response drops at 36 dB/octave.
2 Pole Low Pass (Low Q)
A very classic filter shape. Above what is termed the cut-off frequency, the response drops, at 12
dB/octave. If the Q control is turned up at least some, there will be a resonant peak at the cut-off
frequency. Higher Q's produce higher peaks.
